Vibration at 4000 RPM

Vibration at 4000 RPM
Hello All,
I have noticed that when I put the hammer down, such as in a passing sitution I get a pretty good vibration in the 4000 RPM plus range. It is very prominent in the gas pedal and steering wheel. And this is making it difficult for me to zero in on it.
One thought was that it might be an out of balance driveshaft. But I would find that hard to believe.
This is an 2008 Suburban LTZ, 5.3L
Thanks in advance,
Mike

You may need an alignment. Tires are another possibility. These are simply suggestions, not a diagnosis. I encourage you to take the vehicle in for an inspection. A certified technician will be able to offer a more accurate diagnosis and solution.
Please keep us posted.
If you have any additional questions or concerns, please feel free to contact me.

<o></o>Thanks for the reply. This vehicle was just purchased a few weeks ago from a GM dealer. Does anyone know if I have grounds for this to be looked at on their dime?<o></o>
I know that when I test drove the vehicle it would not return to the straight position coming out of a turn. They did something to somewhat fix it. As in, it's better than it was.<o></o>

MY name is Mike as well. I am a Buick GMC dealer in Columbus, Ohio. As far as inspection and remedy on the dealer's dime - that will most likely be at their disgression, unless you signed some kind of aggreement pertaining to non drivetrain coverage before purchasing.
It can't hurt to reach out and ask the question - just remember the age-old saying, "You catch more flies with sugar than vinegar." If it is something as simple as allignment or tire balance, most reputable GM dealers will be happy to help, or at the very least, advise.
Best of luck

Do you get vibration in Park while reving the motor? Is it only when passing at 4000 RPM?
Depending on your state the dealer may be responsible for repairing this. You could always check and see if the previous owner ever took it in for the same problem.
As stated above, most dealers should be willing to take care of this. Shouldn't hurt to let them give it a look over and check on any previous warranty work.

Could have your vehicle put on a dyno and that would eliminate any alignment issues....
but that is probably a bit extreme... I would start with wheel and tire balancing then alignment...then drive shaft...
Just because its new doesn't mean everything is perfect.. especially tire balancing...a weight could have come off in transport...
